mlxsw: spectrum_buffers: Further reduce pool size on Spectrum-2
In commit e891ce1dd2a5 ("mlxsw: spectrum_buffers: Reduce pool size on Spectrum-2"), pool size was reduced to mitigate a problem in port buffer usage of ports split four ways. It turns out that this work around does not solve the issue, and a further reduction is required. Thus reduce the size of pool 0 by another 2.7 MiB, and round down to the whole number of cells.
